Killing monsters on the blue panels will cause them to turn into Treasure Chests! A great way to get a slew of low-level items to equip on characters. The close Catsabers will aggro pretty readily, but a character will low counter will need to go 'fishing' to aggro the Mothmen and lure them back to the blue area. Don't forget to throw someone across to get the two chests on the island, as they are not there upon map repeat.
